Hi my 15 month old female leopard gecko , Gertie has been acting depressed. I brought her out of her enclosure and noticed that she had little sacs under each of her front legs. I never saw them before. I gently touched them and they are soft to the touch and if they’re sore she didn’t act like it. [Image]

It sounds like it is most likely normal. Leopard geckos can get bulges/sacs under their arms. There seems to be discussion on if they are stored calcium pockets or stored fat/protein. I have read that it may be from over dusting with calcium or from overfeeding. My gecko has had them for many years, they have been larger and very noticeable in the past. Now you can only see them when he moves a certain way. Below is a picture of my leo and his "sac" its a bit hard to see though....does that look like what you are seeing?
